Abstract
A hypothesis, proposed 25 years ago, that there is selection against glycosylation in ruminant pancreatic ribonucleases by replacement of methionine to leucine in the ancestral carbohydrate attachment site Asn-Met-Thr at residues 34-36, was experimentally confirmed. The replacement of leucine at position 35 by methionine in bovine ribonuclease resulted in a three-fold relative increase in glycosylation when expressed in Chinese hamster ovary cells.
